Describing some methods for using piston rods


The piston rod is a connecting component that supports the piston's work, mainly used in the cylinder and pneumatic cylinder motion execution components. It is a frequently moving component with high skill requirements.

Piston RodIt is a connecting component that supports the piston's work, mainly used for the movement of executive components in hydraulic cylinders and pneumatic cylinders. It is a frequently moving component with high skill requirements. Take a hydraulic cylinder as an example: cylinder barrel,Piston Rodpiston, and end cap. The processing quality directly affects the life and stability of the entire product. Its surface roughness requirement is Ra0.4-0.8 μm, and the coaxiality and wear resistance requirements are strict.
The piston rod is processed by rolling, because residual compressive stress remains in the surface layer, which helps to close small cracks on the surface and avoid the expansion of corrosion. This improves the fatigue strength of the cylinder rod. Through roll forming, a cold-worked hardening layer is formed on the rolled surface, reducing the elastic-plastic deformation of the mating surface, thereby improving the wear resistance of the cylinder rod surface and avoiding burn damage caused by grinding. The reduction in surface roughness after rolling can improve the matching performance. At the same time, it reduces the friction damage to the sealing ring or seal during the movement of the cylinder rod piston rod, extending the overall service life of the hydraulic cylinder. The rolling process is a high-quality process measure. Taking a 160mm diameter mirror scraper cutting rolling head as an example, the rolling effect is demonstrated. After rolling, the surface roughness of the cylinder rod is reduced from Ra3.2 before rolling to 6.3μm, and then further reduced to Ra0.4-0.8 μm. The surface hardness of the cylinder rod is increased by about 30%, and the surface fatigue strength of the cylinder rod is increased by 25%.
The above is aboutPiston RodSome methods introduced during use, I hope you can learn more after reading it.

Summary of Experience with Failed Colin Column Balance Adjustment

Analyzing the causes of errors and summarizing lessons learned during work is an important way to improve work efficiency. Fault case: A Hetian injection molding machine's Collin column broke. The Collin column was replaced and the balance was adjusted, without needing any special tools.


Injection Molding Machine Accessories: Detailed Analysis of Common Temperature Problems!

Injection molding machine accessories. In co-ordinated control, the direction of the temperature sensor in the mold is critical. When placing the temperature sensor, the user must consider its shape, structure, and the direction of the cooling channels. In addition, the temperature sensor cannot be placed arbitrarily; it should be placed in an area that has a critical effect on the quality of the injection molded product. There are many ways to connect one or more high-temperature mold temperature controllers to the controller.


Injection Molding Machine Accessories: Standard Maintenance for Injection Molding Machines

Injection molding machine accessories. Everyone should formulate appropriate daily, monthly, and annual maintenance plans based on the condition of the equipment itself, and carefully implement them for each machine according to the plan. Before using the equipment every day, we should check whether each part of the equipment is normal, such as whether the machinery is working normally, whether the heating conditions of each part are normal, whether the circulating water pipes are leaking, whether the emergency stop button can cut off the motor power supply, etc.


What should be noted when repairing a faulty piston rod?

Piston rod failure is normal. The key is to pay attention to the precautions during specific maintenance. If non-professionals perform maintenance, many problems may arise. If possible, choose professional personnel. Maintenance efficiency and its own use value will be higher. We recommend that everyone should understand the following precautions when understanding piston rod maintenance.


What are some applications of piston rods?

In fact, even if we don't mention it, everyone should know quite a bit about piston rods. Of course, to ensure the efficiency of the piston rod, we must guarantee its performance and quality. If more friends are interested in this field, you can also Tel us to discuss your views, I believe this will be helpful to our work.


Connecting structure of piston rod and piston and how to choose piston rod

Piston rods offer significant advantages in practical applications, and the connecting rod structure of the piston is also unique. When used in combination, it is essential to carefully select hydraulic cylinders that demonstrate good operating and production performance. Such products will be highly reliable. The connection structure between the piston rod and piston, and the manufacturing method of the hydraulic cylinder with this piston rod, are essentially the same.


What does the mold pull rod spacing mean in the injection molding machine parameters?

The actual usable area of the template: the greater the distance between the ejector rods, the greater the actual width and height of the grinding tools that can be accommodated. Because injection molding machines need to install plastic injection molds between the moving template and the fixed template, plastic products can be processed. If the mold is to be installed between the two templates, it must pass through two adjacent ejector rods, so the shape of the mold must be smaller than the spacing between the ejector rods.
